Does anyone have any views on learning the same kata across different styles?
Originally I graded to 1st dan in Wado ryu and knew, at least in terms of the moves, all 17 Wado kata. Towards the end of this time, I also started using Shito-Ryu kata as part of my association squad training (the senior instructor paractised both styles but leant on Shito-Ryu for competition) and became interested in the differences. At my 1st dan grading weekend, which was taken by Sensei Harry Cook, I learnt Sanchin and Tensho from Goju-Ryu. I subsequently changed clubs (my original instructor had an issue with me training with other instructors) until I took my 2nd dan in Shotokan, including all the relevant kata up to that standard.
Even now, I use all the versions of each kata that I know. I am well aware that knowing more kata is not an indication of martial skill in and of itself, but it is something I find personally enjoyable. Having said that, I was wondering if I could be biting off more than I can chew, or if it really hurts to know so many kata. I am not talking about mastery of all the kata at this stage, indeed, I am happy to focus in depth on one or two at a time, and claim superior knowledge in them before I move on. But is there anything inherently wrong with wanting to learn two or three different versions of the same kata? Are the applications in the Pinan/Heian versions (for example) fundamentally the same or are they completely different in spirit, and is there anything to gain by studying them all in depth as useful comparisons as I progress?
I look forward to your views,
